The research aimed at utilizing a strategy based on EDJA Model to develop EFL technical writing and critical thinking skills of Higher Institute of Transport Technology (HITT) students. Participants were the fourth-year students at the HITT, Wardan, Giza governorate, Egypt, in the first term of the academic year 2023/2024. The researcher adopted a pre-post experimental one group design. The sample included a group of (37) students selected randomly. Instruments were as follows: a needs analysis questionnaire, a questionnaire of EFL technical writing and critical thinking skills, a pre-posttest of EFL technical writing skill and a rubric to score it, a pre-posttest of EFL critical thinking skills and a rubric to score it, and a Can-Do Checklist. The intervention included (14) sessions for seven weeks (90-minute per session). Results showed that utilizing the strategy based on EDJA model could develop the EFL technical writing and critical thinking skills. Thus, it was highly recommended to implement cooperative learning models, e.g. EDJA in English for Specific Purposes (ESP) programs. Critical thinking instruction should be incorporated in academic study especially technical study field.
